Tacky or Techie? The Tachometer.

There's a gauge that many vehicles have that says RPM on it.  And there are a lot of people who either don't pay any attention to it or don't even know what it is. Here's why it's a good gauge to know about. It's called a tachometer, and that "RPM" label means it is measuring how many revolutions per minute (RPM) the engine is turning.  Automotive experts know that a vehicle's engine can be damaged if it turns too fast (revving too high) or too slowly ("lugging" the engine). A tachometer (sometimes called a tach) is almost a "must-have" gauge for vehicles with a manual transmission; the driver has to manually change gears; the tach helps the driver know when revolutions are in the optimal range. Some say you don't need a tachometer if you drive a vehicle with an automatic transmission. It's true that most drivers of automatics don't even look at it.  But there are times when paying attention to the tach can help you prevent an expensive repair. Here's a good example.&nbs ... read more

When Do My Shocks Need to Be Replaced?

A good suspension system gives a vehicle a smooth, even ride while providing NEWNAN drivers with good handling and control. But like any system on your vehicle, parts of the suspension system can wear out, leading to a lower ride quality and safety concerns. So it's a good idea for drivers in NEWNAN to remember their suspension system in their schedule of preventive maintenance. Springs do most of the work of the suspension system. The most common types of springs are coil and leaf, but air springs and torsion bars are becoming more common. The body of the vehicle is “suspended” by the springs.If springs were the only working component in your suspension system, however, you'd spend your travel time bouncing up and down like a bobblehead. That's where your shocks come in. They keep the rebound, or bounciness, of the springs under control. Shocks also keep your tires on the road, which keeps the driver in control of the vehicle. Some vehicles have struts in their suspension ... read more

What's up with Diesels in NEWNAN?

Would you be surprised to learn that about half of the passenger cars in Europe have diesel engines? You might also be surprised to learn that most manufacturers produce a variety of diesel-fueled cars for purchase abroad.Diesel-fueled vehicles haven't been as popular in the North American markets like GA. But that won't be true for long. North Americans are seeing a lot more diesel-fueled vehicles on the road. And we're not talking about buses and trucks. These vehicles will be passenger cars, pick-ups and SUV's.There are two reasons for this. The first is a recent change in environmental laws that have upgraded emissions standards for diesel fuel in North America. Diesel fuel in North America used to have higher sulfur content than European fuel, meaning that it was a dirtier fuel to burn. That was okay for larger vehicles, but the lighter-weight engines in passenger vehicles just couldn't tolerate it.But that high sulfur content is now a thing of the past. Fue ... read more
